Has L. Ron Hubbard played matchmaker for Tom Cruise? Five months after his rep denied reports linking him to fellow Scientologist Laura Prepon, Page Six says the "Dianetics"-devoted twosome are "still seeing each other."

And much like the story of Xenu, they're "being extremely careful to keep it secret." Alas, much like Cruise's marriage to Katie Holmes, the stealthy plan doesn't seem to be working out very well.

According to the paper, the relationship is "the buzz on the set" of Prepon's acclaimed prison series, "Orange Is the New Black."

Their reps, however, continue to deny a romantic connection.

Relationship rumors first surfaced in late November, when Grazia magazine shared a suspicious amount of detail about how Tom, 51, treated Laura, 34, to an elaborate first date at the Renaissance, an eatery inside the Church of Scientology's Celebrity Centre in Los Angeles.

"He had her picked up in a vintage car, knowing it was one of her favorites, and had pre-ordered a vintage bottle of 1979 merlot, which was on the table when she arrived," relayed an insider. "They spent three hours laughing and joking. It's clear Tom is smitten, and after the date he was on cloud nine."

Seems Cruise had "always been fascinated by her and, since seeing her in 'Orange Is the New Black,' that has turned into an attraction. So he bit the bullet and asked her out on a formal date."

They were reportedly spotted on a second date at the restaurant, followed by an appearance at a party thrown at the home of fellow Operating Thetans John Travolta and Kelly Preston.

The thrice-married Cruise has kept a low profile dating-wise since Holmes blindsided him with divorce papers in June of 2012, a move she allegedly made in part because she was worried about daughter Suri's involvement with the church.

If the Prepon rumblings turn out to be true (the National Enquirer recently hinted about him being set up with "Mad Men" star -- and Scientologist -- Elisabeth Moss), Cruise would be squiring yet another statuesque squeeze: At 5'10, Laura falls right in between Katie (5'9) and his second wife, Nicole Kidman (5'11).

Laura is no stranger to dating inside the church, having spent several years with Christopher Masterson, the brother of her former "That '70s Show" co-star Danny Masterson.
